Seta-750-NHS (K8-7522) is a hydrophilic, amine-reactive label containing one NHS-ester group with almost identical absorption and emission as Cy7 or Alexa 750 and can therefore be used with these filter sets. It combines high photostability and brightness. Its extinction coefficient is 230,000 M–1cm–1.
Applications
Covalent labeling of proteins, amino-modified DNA and amino-modified oligonucleotides
Fluorescence intensity and fluorescence polarization-based applications
Resonance Energy Transfer (RET)
Flow Cytometry
Immunofluorescence
Gene Expression
Homogeneous Assays
Microarrays
Advantages
Perfectly suited for excitation with the 680, 700 or 750 nm diode lasers
Sensitive; high extinction coefficients and high quantum yields
pH-insensitive between pH 3 and pH 10
Good aqueous solubility; this label does not alter the solubility of bioconjugates
High photostability; e.g. compared to fluorescein or Cy7
Low molecular weight — Seta-750 does not add substantial mass to the conjugates
Ideal for non-radioactive labeling of proteins, amino-modified oligonucleotides and amino-modified lipids
